CHANCE OF LIGHT SHOWERS BEFORE NOON

Hurricane Fabio leftovers should arrive today, and there’s a slight chance that they will dump record-tying rainfall on San Diego.

But no need to rush out and buy flood insurance or ready the rowboat. San Diego’s rainfall record for July 18 is 0.01 of an inch, set in 1922.

The leading edge of the cloud mass associated with what used to be Fabio should pass over the county’s southern coast sometime before noon, and that’s when the city will have the best chance for light showers. National Weather Service forecaster Joe Dandrea said it’s unlikely that more than 0.01 of an inch will be recorded at the beaches, but the mountains could get a few hundredths more. There’s also a very slight chance of thunderstorms.

“There’s not a whole lot of moisture that will fall out of this thing,” Dandrea said.

It may feel a bit more humid today, Dandrea said, but most of the moisture from the former hurricane will be in the form of midlevel and high clouds, which should linger through Thursday morning. Coastal highs today should be in the mid 70s, and the inland valleys should reach the low 80s.

San Diego has another slight chance of rain over the weekend and early next week. Monsoonal moisture moving up from Mexico should generate thunderstorms over the mountains and deserts, and upper-level winds from the east could push storms west of the mountains.

On Monday, it would only take another 0.01 of an inch of rain to match the daily record for July 23. San Diego averages just 0.03 of an inch of rain for all of July.
